docs: close the plan-bookkeeping drift and state the tier truth (§8.5, §8.6, #522)

Bookkeeping: 13 .tasks.json files closed — the 8 the audit named, plus
mesh-phase4 (Task 9 landed 3a590a0c), the 4th stillpending phase file, and
historian-tcp-transport closed as OBSOLETE (it targets the retired Wonderware
sidecar; there is no Wonderware backend in the tree). Each carries a
closureNote naming the evidence rather than just a status flip.

11 archreview live gates written back from STATUS.md, which had recorded them
passed since 2026-07-13/15 without ever updating the task files: R2-01 #11,
R2-02 #15/#18, R2-05 T15, R2-06 T12, R2-07 T5/T6/T12/T14, R2-11 T22/T24.

R2-03 and R2-10 were deliberately NOT closed. STATUS.md's headline says "every
Round-2 live gate is now GREEN", but its own per-item detail says R2-03 is
"live-blocked on this data-less rig" and R2-10 verified the pipeline with
"breaker-OPEN state not forced". Both now carry an openNote recording the
actual blocker.

The point of the sweep: ~140 phantom pending tasks are gone, so the genuinely
unexecuted 19-task AdminUI follow-ups plan is now the largest open item in
docs/plans/ instead of being buried under work that shipped months ago.

Tier truth: docs/v2/driver-stability.md now states that its tier table is
aspirational — every driver runs Tier A because no factory passes a tier, so
MemoryRecycle and ScheduledRecycleScheduler have never engaged, and the config
parser validates a RecycleIntervalSeconds that does nothing. It also corrects a
staleness the audit missed: the separate-Windows-service hosting it describes
for Tier C no longer exists (Galaxy moved to the mxaccessgw sidecar in PR 7.2,
FOCAS went in-process with its managed wire client). docs/drivers/README.md
already said Tier A for both, so the two no longer contradict.

No runtime change — enabling recycle on two live drivers wants its own live
gate, not a docs-pass side effect. Keep-or-delete tracked as Gitea #522.
